an improved banding device whereby both the underlying and overlyingends of the band, after it has been placed around the cigar, will besnugly held around the cigar and which is particularly adapted for bandshaving one end wider than the other.

1 'A further object of the invention is to provide a simple device forsnugly wrapping bands around cigars,and which is particularly adapted towrap cigars of irregular shape and different sizes.

A further object of the invention is toprovide an improved bandingdevice comprising flexible tapes, in which the cigar is held upon asupport, and which is operable in such manner that a cigar will not rollin or on the tapes and so that the relative position between the cigarsof a row will not-be disturbed.

A still further object of the invention is to provide an improved cigarbanding machine comprising mechanism for packing the cigars in boxes andin which theciga-rs are fed through the machine in such manner thattheir relative position will not be disturbed, and so that whenpreviously boxed cigars are supplied to the bandingmechanism, in thesame order as they occupied in the box, they will be packed inrows com-,

The improved banding-machine comprises a table 30 upon which the cigarsto be banded will be fed, is adapted to apply bands cut from acontinuous strip 31 of bands drawn from a roll 32, and comprisesmechanism for feeding the cigars supplied to the table 30, to deviceswhich will suecessively apply the bands severed from the web, as thecigars are delivered to the banding-mcchanism, mechanism for feedingrows of banded cigars to mechanism'which which they have assumed in theboxes.

packsthem in boxes, and mechanism for laying a strip of paraliin paperbetween the rows of cigars as they are packed. ,The present machine isdesigned to receive cigars which have been packed in boxes and to applybands to the cigars after they have been packed, so that the bands willbe applied to the cigars in the resultant shapps t has been found inpractice that if bands are applied to the cigars before they have beenpacked, the bands will become loose and irregular after the cigars arepacked, so that the bands will not fit snugly around the cigars. Thecigars which have been packed are laid upon the table in rows taken fromthe boxes, the cigars remaining in the order in which they are arrangedwhen in the boxes, each row being laid in succession upon the table. Thepurpose of maintaining this order is to cause the banded cigars to bedelivered into the or a like box from which they have been taken, in theinverse order in which they are removed therefrom, by thepacking-mechanism. Feed-table 30 comprises a stationary central plate 33which is suitably secured to the frame A of the machine 'andreciprocable plates 34 at the sides ofthe plate 33 (Fig. 2). Beneatheach plate 34:", a pair of guide-rods 35 (Figs. 4 and 15) are secured inlugs 37 of the frame. Each plate 31 is pivotally connected as at 38 tocollars 39 which are slidably mounted on rods 35, and is operatedlongitudinally to move the cigars toward the band-applying mechanism,and vertically to cause them to engage and lift the cigars on thein-stroke, and downwardly to clear the cigars during the return or outstroke of the bars. For this purpose,,each plate has secured to itsunderside, brackets 40 (Figs. 1, 13, 14: and 15) which are connectedtoslidable collars 41 on rods 35, by pivot-pins 42 45 held in said collarsand extending into slots 13 in said brackets. In each bracket 40, alever 44 is pivoted on cross-pin 45 which extends between a pair ofcollars 41, and each lever 44 is provided with abutments or cams 44:

which are adapted to engage one of the plates 34, and raise it duringthe initial part of the iii-stroke of the plate. Brackets -10areprovided with abutmcnts 10 for levers -11, which will be engaged bythe lovers to cause plates 3% to be operated longitudinally by the leverafter the plate has been initially raised by cams 41. As levers -11- areoperated inwardly by rods 27, they will initially swing on their pivots4:5 and raise the outer ends of the plates 34, the latter swinging abouton their pivots 38 (Fig. 4:) until the levers engage 'abutments 10. Thenthe plates will be operated longitudinally by rods 27 and levers a1.During retraction of the plates 34 levers 524: will initially swingabout their pivots to lower cams 44 and the plates, and thereafter saidlevers will engage abutments 41 on collars 41, and cause the plates tomove outwardly in lowered relation to stationary plate 33. Rods 27 areadjust-ably connected as at 28, to arms 29 which are secured to arock-shaft 77 which is operated by mechanism hereinafter set forth. Inoperation, bars 31 will be reciprocated and operated to advance theentire row of cigars on the feed-table, so that the foremost cigars willbe successively fed to the bandin -mechanism. The cigars on table 30 arefed forwardly intermittently toward a stationary abutment 45 (Figs. 3and 5) which arrests the cigars and positions the foremost one in thepath of a plunger 48 which is adapted to deliver the cigars to thebanding-mechanism. The cigars on the feed-table, when reaching abutment45 pass onto two oppositely disposed spring-pressed gates (Figs.

4, 5, and 6) 46 and 47 which are adapted to support the cigars inposition beneath plunger 18 and to swing downwardly when the cigar isbeing forced into the banding-mechanism by plunger 48. These gatesyieldingly hold the cigars until a banding device is ready to receiveone, and guide them into the banding-devices.

The several mechanisms of the machine are driven by a motor 66 (Figs. 7and 8) which is mounted upon the base A of frame A and the shaft 67 ofsaid motor has a small friction pulley 68 which engages the face of afriction-wheel 69 on a shaft 70 which is adapted to drive a pinion 71which meshes with a gear wheel 72 on the main drive-shaft 73 of themachine (Fig. 3).

The bands supplied to the machine are on a continuous strip 31 ofconnected bands, wound on a roll 32. This strip passes under aguide-roller 49 which is journaled in the frame, and thence between apair of endless feed-belts 50, 51, which serve to inter' mittently feeda portion of the strip corresponding to the length of a band, across thepath of the cigars lowered by plunger 48 (Fig. 4). The upper belt 50passes around rolls 52 and 53 both of which are
